Kaijun He (何恺骏) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 3.47, set at Lishui University Open 2018, puts him in the top 5.3% of the 129,321 people who have ever been ranked in the event, and 639th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 3 competitions since November 2016, he has put 34 official solves on the record across two events. His Pyraminx best has come down from 7.70 in April 2017 to 3.47, a 55% improvement. Kaijun has entered three competitions, more competitions than 69% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
